GE’s Foil Electrode capacitors are manufactured
with sheets of high quality aluminum foil as the
electrodes. The dielectric consists of two sheets of
polypropylene film. The film is manufactured in GE’s
own Capacitor Materials Operation. It is specially
designed with a rough surface to allow full impregna-
tion by the dielectric fluid. The aluminum foil elec-
trodes extend, one on each end of the capacitor roll,
so that a solder connection can be made. Depending
on the typical current for the type of capacitor, the
internal connections from the roll ends to the termi-
nals are either braided cables or tin-plated copper
straps. This construction provides capacitors that are
inherently capable of handling high RMS and peak
currents.
DIELECTRIC FLUIDS
All of GE’s dielectric fluids are chosen for
specific characteristics that match the other
components in the capacitor dielectric system and the
applications for which the capacitors are intended.
Each fluid is based on one or two major
constituents and blended with proprietary
additives for optimum performance.
Dielectrol VII
A Benzyl Toluene-based fluid, used for film/foil
high current products.
GE’s Film/Paper/Foil capacitors are manufactured
with high grade film and foil, and capacitor grade kraft
paper. They are typically high voltage DC rated and
are treated with Geconol capacitor dielectric fluid.
These capacitors are exposed foil construction for
use in snubber and or DC filtering applications.
